Abstract
A photoelectric conversion device includes: a photon detection element configured to generate a light reception pulse signal according to incident light; a control unit configured to control a light emission pulse pattern of a light source, a light emission timing of the light source, and a gating period with respect to the light emission timing; a gating unit configured to output a light reception pulse pattern of the incident light based on the light reception pulse signal that is input in the gating period; and a pattern detection unit configured to compare the light reception pulse pattern with the light emission pulse pattern to output a signal according to a comparison result. A length of the gating period is equal to or greater than a length of a duration of the light emission pulse pattern.
